BACKGROUND

Aspects of the present disclosure relate generally to wirelesscommunication networks, and more particularly, to downlink and uplinkcontrol management of component carriers during carrier aggregation in anew radio wireless communication system.

Wireless communication networks are widely deployed to provide varioustypes of communication content such as voice, video, packet data,messaging, broadcast, and so on. These systems may be multiple-accesssystems capable of supporting communication with multiple users bysharing the available system resources (e.g., time, frequency, andpower). Examples of such multiple-access systems include code-divisionmultiple access (CDMA) systems, time-division multiple access (TDMA)systems, frequency-division multiple access (FDMA) systems, orthogonalfrequency-division multiple access (OFDMA) systems, and single-carrierfrequency division multiple access (SC-FDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. For example, a fifth generation (5G)wireless communications technology (which can be referred to as newradio (NR)) is envisaged to expand and support diverse usage scenariosand applications with respect to current mobile network generations. Inan aspect, 5G communications technology can include: enhanced mobilebroadband addressing human-centric use cases for access to multimediacontent, services and data; ultra-reliable-low latency communications(URLLC) with certain specifications for latency and reliability; andmassive machine type communications, which can allow a very large numberof connected devices and transmission of a relatively low volume ofnon-delay-sensitive information. As the demand for mobile broadbandaccess continues to increase, however, further improvements in NRcommunications technology and beyond may be desired.

For example, for NR communications technology and beyond, improvementsin downlink and uplink control management of component carriers duringcarrier aggregation may be desired.

DETAILED DESCRIPTION

Various aspects are now described with reference to the drawings. In thefollowing description, for purposes of explanation, numerous specificdetails are set forth in order to provide a thorough understanding ofone or more aspects. It may be evident, however, that such aspect(s) maybe practiced without these specific details. Additionally, the term“component” as used herein may be one of the parts that make up asystem, may be hardware, firmware, and/or software stored on acomputer-readable medium, and may be divided into other components.

The present disclosure generally relates to downlink and uplink controlmanagement of component carriers during carrier aggregation in a newradio wireless communication system. In an example, current LTE carrieraggregation configurations includes frequency division duplex (FDD)+FDD(Rel-10), time division duplex (TDD) +TDD of same subframe configuration(Rel-10), TDD+TDD of different subframe configurations (Rel-11), FDD+TDD(Rel-12), and from 5 to 32 component carriers in carrier aggregation(Rel-13). Specifically for the downlink, same and cross-carrierscheduling occurs. This includes Pcell only (pScell in dualconnectivity) common search space (CSS) monitoring, channel stateinformation (CSI) measurement, reporting, processing limitations,collision handling, etc. (e.g., Physical Control Format IndicatorChannel (PCFICH)/Physical Hybrid-ARQ Indicator Channel (PHICH), softerbuffer management). For the uplink, this includes Pcell only (pScell indual-Physical Uplink Control Channel (PUCCH) carrier aggregation or dualconnectivity) PUCCH transmission, various PUCCH formats (1/2/3/4/5),single PUSCH for UCI handling, etc. (e.g., SRS/PUCCH//Physical UplinkShared Channel (PUSCH)/multiple Timing Advance Groups (TAGs)/etc.). Assuch, for LTE carrier aggregation, the same subframe structure andnumerology are used. Moreover, in LTE Rel-14, the introduction of sTTIenables carrier aggregation with sTTI and 1-ms.

Accordingly, for new radio wireless communication systems a need existsfor utilizing different slot durations and numerologies. For example,new radio wireless communication systems need to cover a wide range ofcarrier frequencies, such as, sub-6 GHz and/or millimeter waves.Further, new radio wireless communication systems require different slotdurations, such as, 0.5 ms slot, 0.25 ms slot, etc. Moreover, new radiowireless communication systems require different numerologies/tonespacings, such as, 15 kHz, 30 kHz, 60 kHz, 120 kHz, etc. Therefore,carrier aggregation and dual connectivity for new radio wirelesscommunication systems need to accommodate different numerologies indifferent component carriers configured for a UE.

In an implementation at the network (e.g., gNB), according to oneexample, a method of wireless communication may include generating, at anetwork entity (e.g., gNB), a slot format indicator for at least onecomponent carrier, each component carrier including a group commonPDCCH, the slot format indicator indicating at least slot structureinformation for one or more other component carriers within the groupcommon PDCCH, and transmitting, to a UE, the slot format indicator in atleast one slot of the at least one component carrier. Another method mayinclude determining, at a network entity, whether cross-carrierscheduling for two or more component carriers with differentnumerologies is enabled, generating at least one DCI for at least one ofthe two or more component carriers based on a determination thatcross-carrier scheduling is enabled, the DCI indicating at least slotstructure information for one or more other component carriers of thetwo or more component carriers, and transmitting, to a UE, the at leastone DCI in at least one slot of the at least one of the two or morecomponent carriers. Another method may include assigning, at a networkentity, a component carrier to a timing advance group based on one ormore carrier characteristics of the component carrier, the timingadvance group including one or more component carriers and a timingadvance offset associated with each of the one or more componentcarriers, and transmitting, to a UE, the timing advance offsetassociated with the component carrier.

In an implementation at a UE, an example method of wirelesscommunications includes receiving, at a UE, an indication to trigger CSImeasurements in at least two or more component carriers, the indicationincluded within DCI received in a slot of one of the at least two ormore component carriers, determining a measurement configuration forperforming the CSI measurements in the at least two or more componentcarriers, performing the CSI measurements in the at least two or morecomponent carriers based on the measurement configuration, andtransmitting, to a network entity, the CSI measurements for the at leasttwo or more component carriers. Another method includes generating, at aUE, UCI for at least one component carrier, the UCI including uplinkinformation for at least one or more other component carriers, andtransmitting, to a network entity, the UCI in at least one slot of theat least one component carrier.

Additional features of the present aspects are described in more detailbelow with respect to FIGS. 1-17.

It should be noted that the techniques described herein may be used forvarious wireless communication networks such as CDMA, TDMA, FDMA, OFDMA,SC-FDMA, and other systems. The terms “system” and “network” are oftenused interchangeably. A CDMA system may implement a radio technologysuch as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc.CDMA2000 covers IS-2000, IS-95, and IS-856 standards. IS-2000 Releases 0and A are commonly referred to as CDMA2000 1×, 1×, etc. IS-856 (TIA-856)is commonly referred to as CDMA2000 1×EV-DO, High Rate Packet Data(HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other variants ofCDMA. A TDMA system may implement a radio technology such as GlobalSystem for Mobile Communications (GSM). An OFDMA system may implement aradio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA(E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20,Flash-OFDM™, etc. UTRA and E-UTRA are part of Universal MobileTelecommunication System (UMTS). 3GPP Long Term Evolution (LTE) andLTE-Advanced (LTE-A) are new releases of UMTS that use E-UTRA. UTRA,E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from anorganization named “3rd Generation Partnership Project” (3GPP). CDMA2000and UMB are described in documents from an organization named “3rdGeneration Partnership Project 2” (3GPP2). The techniques describedherein may be used for the systems and radio technologies mentionedabove as well as other systems and radio technologies, includingcellular (e.g., LTE) communications over a shared radio frequencyspectrum band. The description below, however, describes an LTE/LTE-Asystem for purposes of example, and LTE terminology is used in much ofthe description below, although the techniques are applicable beyondLTE/LTE-A applications (e.g., to 5G networks or other next generationcommunication systems).

The following description provides examples, and is not limiting of thescope, applicability, or examples set forth in the claims. Changes maybe made in the function and arrangement of elements discussed withoutdeparting from the scope of the disclosure. Various examples may omit,substitute, or add various procedures or components as appropriate. Forinstance, the methods described may be performed in an order differentfrom that described, and various steps may be added, omitted, orcombined. Also, features described with respect to some examples may becombined in other examples.

The base station 105 may execute the downlink controlmanagement component 170 to generate at least one Downlink ControlInformation (DCI) 174 for at least one of the two or more componentcarriers based on a determination that cross-carrier scheduling isenabled. The DCI 174 indicates at least slot structure information forone or more other component carriers of the two or more componentcarriers. The base station 105 may execute the downlink controlmanagement component 170 to transmit the at least one DCI 174 in atleast one slot of the at least one of the two or more componentcarriers.

In an aspect, the base station 105 may execute the downlink controlmanagement component 170 to assign a component carrier to a timingadvance group based on one or more carrier characteristics of thecomponent carrier, the timing advance group including one or morecomponent carriers and a timing advance offset 176 associated with eachof the one or more component carriers. The base station 105 may executethe downlink control management component 170 to transmit the timingadvance offset 176 associated with the component carrier.

The UE 110 mayexecute the uplink control management component 150 to determine ameasurement configuration for performing the CSI measurements 152 in theat least two or more component carriers. The UE 110 may execute theuplink control management component 150 to perform the CSI measurements152 in the at least two or more component carriers based on themeasurement configuration. The UE 110 may execute the uplink controlmanagement component 150 to transmit the CSI measurements 152 for the atleast two or more component carriers.

In aspect, the UE 110 may execute the uplink control managementcomponent 150 to generate an Uplink Control Information (UCI) 154 for atleast one component carrier, the UCI 154 including uplink informationfor at least one or more other component carriers. The UE 110 mayexecute the uplink control management component 150 to transmit the UCI154 in at least one slot of the at least one component carrier.

The wireless communication network 100 may include one or more basestations 105, one or more UEs 110, and a core network 115. The corenetwork 115 may provide user authentication, access authorization,tracking, internet protocol (IP) connectivity, and other access,routing, or mobility functions. The base stations 105 may interface withthe core network 115 through backhaul links 120 (e.g., S1, etc.). Thebase stations 105 may perform radio configuration and scheduling forcommunication with the UEs 110, or may operate under the control of abase station controller (not shown). In various examples, the basestations 105 may communicate, either directly or indirectly (e.g.,through core network 115), with one another over backhaul links 125(e.g., X1, etc.), which may be wired or wireless communication links.

The base stations 105 may wirelessly communicate with the UEs 110 viaone or more base station antennas. Each of the base stations 105 mayprovide communication coverage for a respective geographic coverage area130. In some examples, base stations 105 may be referred to as a basetransceiver station, a radio base station, an access point, an accessnode, a radio transceiver, a NodeB, eNodeB (eNB), gNodeB (gNB), HomeNodeB, a Home eNodeB, a relay, or some other suitable terminology. Thegeographic coverage area 130 for a base station 105 may be divided intosectors or cells making up only a portion of the coverage area (notshown). The wireless communication network 100 may include base stations105 of different types (e.g., macro base stations or small cell basestations, described below). Additionally, the plurality of base stations105 may operate according to different ones of a plurality ofcommunication technologies (e.g., 5G (New Radio or “NR”), fourthgeneration (4G)/LTE, 3G, Wi-Fi, Bluetooth, etc.), and thus there may beoverlapping geographic coverage areas 130 for different communicationtechnologies.

In some examples, the wireless communication network 100 may be orinclude one or any combination of communication technologies, includinga new radio (NR) or 5G technology, a Long Term Evolution (LTE) orLTE-Advanced (LTE-A) or MuLTEfire technology, a Wi-Fi technology, aBluetooth technology, or any other long or short range wirelesscommunication technology. In LTE/LTE-A/MuLTEfire networks, the termevolved node B (eNB) may be generally used to describe the base stations105, while the term UE may be generally used to describe the UEs 110.The wireless communication network 100 may be a heterogeneous technologynetwork in which different types of eNBs provide coverage for variousgeographical regions. For example, each eNB or base station 105 mayprovide communication coverage for a macro cell, a small cell, or othertypes of cell. The term “cell” is a 3GPP term that can be used todescribe a base station, a carrier or component carrier associated witha base station, or a coverage area (e.g., sector, etc.) of a carrier orbase station, depending on context.

A macro cell may generally cover a relatively large geographic area(e.g., several kilometers in radius) and may allow unrestricted accessby the UEs 110 with service subscriptions with the network provider.

A small cell may include a relative lower transmit-powered base station,as compared with a macro cell, that may operate in the same or differentfrequency bands (e.g., licensed, unlicensed, etc.) as macro cells. Smallcells may include pico cells, femto cells, and micro cells according tovarious examples. A pico cell, for example, may cover a small geographicarea and may allow unrestricted access by the UEs 110 with servicesubscriptions with the network provider. A femto cell may also cover asmall geographic area (e.g., a home) and may provide restricted accessand/or unrestricted access by the UEs 110 having an association with thefemto cell (e.g., in the restricted access case, the UEs 110 in a closedsubscriber group (CSG) of the base station 105, which may include theUEs 110 for users in the home, and the like). A micro cell may cover ageographic area larger than a pico cell and a femto cell, but smallerthan a macro cell. An eNB for a macro cell may be referred to as a macroeNB. An eNB for a small cell may be referred to as a small cell eNB, apico eNB, a femto eNB, or a home eNB. An eNB may support one or multiple(e.g., two, three, four, and the like) cells (e.g., component carriers).

The communication networks that may accommodate some of the variousdisclosed examples may be packet-based networks that operate accordingto a layered protocol stack and data in the user plane may be based onthe IP. A user plane protocol stack (e.g., packet data convergenceprotocol (PDCP), radio link control (RLC), MAC, etc.), may performpacket segmentation and reassembly to communicate over logical channels.For example, a MAC layer may perform priority handling and multiplexingof logical channels into transport channels. The MAC layer may also usehybrid automatic repeat/request (HARD) to provide retransmission at theMAC layer to improve link efficiency. In the control plane, the RRCprotocol layer may provide establishment, configuration, and maintenanceof an RRC connection between a UE 110 and the base station 105. The RRCprotocol layer may also be used for core network 115 support of radiobearers for the user plane data. At the physical (PHY) layer, thetransport channels may be mapped to physical channels.

The UEs 110 may be dispersed throughout the wireless communicationnetwork 100, and each UE 110 may be stationary or mobile. A UE 110 mayalso include or be referred to by those skilled in the art as a mobilestation, a subscriber station, a mobile unit, a subscriber unit, awireless unit, a remote unit, a mobile device, a wireless device, awireless communications device, a remote device, a mobile subscriberstation, an access terminal, a mobile terminal, a wireless terminal, aremote terminal, a handset, a user agent, a mobile client, a client, orsome other suitable terminology. A UE 110 may be a cellular phone, asmart phone, a personal digital assistant (PDA), a wireless modem, awireless communication device, a handheld device, a tablet computer, alaptop computer, a cordless phone, a smart watch, a wireless local loop(WLL) station, an entertainment device, a vehicular component, acustomer premises equipment (CPE), or any device capable ofcommunicating in wireless communication network 100. Additionally, a UE110 may be Internet of Things (IoT) and/or machine-to-machine (M2M) typeof device, e.g., a low power, low data rate (relative to a wirelessphone, for example) type of device, that may in some aspects communicateinfrequently with wireless communication network 100 or other UEs. A UE110 may be able to communicate with various types of base stations 105and network equipment including macro eNBs, small cell eNBs, macro gNBs,small cell gNBs, relay base stations, and the like.

The UE 110 may be configured to establish one or more wirelesscommunication links 135 with one or more base stations 105. The wirelesscommunication links 135 shown in wireless communication network 100 maycarry uplink (UL) transmissions from a UE 110 to a base station 105, ordownlink (DL) transmissions, from a base station 105 to a UE 110. Thedownlink transmissions may also be called forward link transmissionswhile the uplink transmissions may also be called reverse linktransmissions. Each wireless communication link 135 may include one ormore carriers, where each carrier may be a signal made up of multiplesub-carriers (e.g., waveform signals of different frequencies) modulatedaccording to the various radio technologies described above. Eachmodulated signal may be sent on a different sub-carrier and may carrycontrol information (e.g., reference signals, control channels, etc.),overhead information, user data, etc. In an aspect, the wirelesscommunication links 135 may transmit bidirectional communications usingfrequency division duplex (FDD) (e.g., using paired spectrum resources)or time division duplex (TDD) operation (e.g., using unpaired spectrumresources). Frame structures may be defined for FDD (e.g., framestructure type 1) and TDD (e.g., frame structure type 2). Moreover, insome aspects, the wireless communication links 135 may represent one ormore broadcast channels.

In some aspects of the wireless communication network 100, the basestations 105 or UEs 110 may include multiple antennas for employingantenna diversity schemes to improve communication quality andreliability between base stations 105 and UEs 110. Additionally oralternatively, base stations 105 or UEs 110 may employ multiple inputmultiple output (MIMO) techniques that may take advantage of multi-pathenvironments to transmit multiple spatial layers carrying the same ordifferent coded data.

The wireless communication network 100 may support operation on multiplecells or carriers, a feature which may be referred to as carrieraggregation (CA) or multi-carrier operation. A carrier may also bereferred to as a component carrier (CC), a layer, a channel, etc. Theterms “carrier,” “component carrier,” “cell,” and “channel” may be usedinterchangeably herein. A UE 110 may be configured with multipledownlink CCs and one or more uplink CCs for carrier aggregation. Carrieraggregation may be used with both FDD and TDD component carriers. Thebase stations 105 and UEs 110 may use spectrum up to Y MHz (e.g., Y=5,10, 15, or 20 MHz) bandwidth per carrier allocated in a carrieraggregation of up to a total of Yx MHz (x=number of component carriers)used for transmission in each direction. The carriers may or may not beadjacent to each other. Allocation of carriers may be asymmetric withrespect to DL and UL (e.g., more or less carriers may be allocated forDL than for UL). The component carriers may include a primary componentcarrier and one or more secondary component carriers. A primarycomponent carrier may be referred to as a primary cell (PCell) and asecondary component carrier may be referred to as a secondary cell(SCell).

The wireless communications network 100 may further include basestations 105 operating according to Wi-Fi technology, e.g., Wi-Fi accesspoints, in communication with UEs 110 operating according to Wi-Fitechnology, e.g., Wi-Fi stations (STAs) via communication links in anunlicensed frequency spectrum (e.g., 5 GHz). When communicating in anunlicensed frequency spectrum, the STAs and AP may perform a clearchannel assessment (CCA) or listen before talk (LBT) procedure prior tocommunicating in order to determine whether the channel is available.

Additionally, one or more of base stations 105 and/or UEs 110 mayoperate according to a NR or 5G technology referred to as millimeterwave (mmW or mmwave or MMW) technology. For example, mmW technologyincludes transmissions in mmW frequencies and/or near mmW frequencies.Extremely high frequency (EHF) is part of the radio frequency (RF) inthe electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and awavelength between 1 millimeter and 10 millimeters. Radio waves in thisband may be referred to as a millimeter wave. Near mmW may extend downto a frequency of 3 GHz with a wavelength of 100 millimeters. Forexample, the super high frequency (SHF) band extends between 3 GHz and30 GHz, and may also be referred to as centimeter wave. Communicationsusing the mmW and/or near mmW radio frequency band has extremely highpath loss and a short range. As such, base stations 105 and/or UEs 110operating according to the mmW technology may utilize beamforming intheir transmissions to compensate for the extremely high path loss andshort range.

Referring to FIG. 2, a conceptual diagram of example downlink centricslot structures 200 for at least two component carriers with differentnumerologies based on the techniques described herein. For example, theUE 110 may execute the uplink control management component 150 and thebase station 105 may execute the downlink control management component170 to communicate via component carriers CC1 and CC2 using carrieraggregation based on the downlink centric slot structures 200 describedherein.

In this example of the downlink centric slot structures 200, thenumerologies of CC1 and CC2 are described. CC1 may be configured with aslot length x (e.g., 0.5 ms) while CC2 may be configured with a slotlengthy (e.g., 0.25 ms). Further, CC1 may be configured with 30 kHz tonespacing and 14 symbols for each slot. CC2 may be configured with 60 kHztone spacing and 14 symbols for each slot. In another example, componentcarrier with 60 kHz may still be configured with a 0.5 s slot, but mayhave different transmission time intervals (TTI) for scheduling.

In an aspect, each slot of each component carrier may be configured witha number of regions, including a downlink control region, a downlinkdata region, a gap region, and an uplink control region. In an example,the gap region corresponds to a region in which no transmissions occurbetween the UE 110 and base station 105.

Referring to FIG. 3, a conceptual diagram of example slot structures 300for multiple time division duplex (TDD) downlink and uplink slots isdescribed. In an aspect, for TDD downlink centric slot, the slotstructure may include downlink burst regions with a portion designatedfor PDCCH. The TDD downlink centric slot may also include an uplinkcontrol region with a portion designated for PUCCH. In an aspect, for aTDD downlink only slot, the slot structure may include downlink burstregions with a portion designated for PDCCH. Unlike the TDD downlinkcentric slot, the TDD downlink only slot does not include an uplinkcontrol region.

In an aspect, for a TDD uplink centric slot, the slot structure mayinclude uplink burst regions with one or more portions designated forPUCCH. The TDD uplink centric slot may also include a downlink burstregion with a portion designated for PDCCH. In an aspect, for a TDDuplink only slot, the slot structure may include uplink burst regionswith one or more portions designated for PUCCH. Unlike the TDD uplinkcentric slot, the TDD uplink only slot does not include a downlink burstregion.

Referring to FIGS. 4 and 5, conceptual diagrams of example downlinkcentric slot structures 400 and 500 during transmission of across-carrier indicator for multiple component carriers with a groupcommon PDCCH and different numerologies are described. A network entity,such as base station 105 (FIG. 1) may execute the downlink controlmanagement component 170 to configure a component carrier (e.g., CC1)with a longer time duration to schedule a component carrier (e.g., CC2)with a shorter time duration or vice versa.

For example, CC1 may be configured with a slot k of a slot length (e.g.,0.5 ms) while CC2 may be configured with a slots 2 n and 2 n+1, eachwith a slot length (e.g., 0.25 ms). Further, CC1 may be configured with30 kHz tone spacing and 14 symbols for each slot. CC2 may be configuredwith 60 kHz tone spacing and 14 symbols for each slot. In anotherexample, component carrier with 60 kHz may still be configured with a0.5 s slot, but may have a different TTI for scheduling.

In an aspect, with regard to downlink centric slot structure 400, forCase 1, a component carrier (e.g., CC2) with a shorter-slot durationcarrying group common PDCCH (or a.k.a. PSFICH (Physical Slot FormatIndicator Channel)) indicating for a component carrier (e.g., CC1) witha longer-slot-duration. For example, cross-carrier group common PDCCHmay be enabled only in a subset of slots (e.g., slots 2 n in CC2 maycarry the cross-carrier group common PDCCH for CC1).

In an aspect, for Case 2, a component carrier (e.g., CC1) with alonger-slot duration carrying group common PDCCH indicating for acomponent carrier (e.g., CC2) with a shorter-slot-duration. For example,cross-carrier group common PDCCH may be enabled to indicate two or moreslots in one group common PDCCH for the cross-carrier indicatedcomponent carrier (e.g., where group common PDCCH in slot k of CC1indicates the slot structures of slot 2 n and slot 2 n+1 for CC2).Further, in another example, slot 2 n and slot 2 n+1 may be restrictedto have the same slot structure, such as, a single indicator for CC2. Inanother example, another group common PDCCH channel is enabled on CC1 inthe middle of the slot. In a further example, for CC2 slot 2 n,cross-carrier may be indicated by group common PDCCH on CC1, but for CC2slot 2 n+1, it is same-carrier indicated by group common PDCCH on CC2.Then group common PDCCH for CC2 is only present in odd slots.

In some aspects, Case 1 and Case 2 for a combination of componentcarriers may change dynamically if the slot structure(s) of componentcarrier(s) in carrier aggregation and dual connectivity changedynamically. For example, CC1 may cross-carrier indicate the slotstructure for CC2, but CC1's slot duration may be longer and/or shorterat a given time instance depending on the dynamic slot durationmanagement at CC1 and/or CC2.

In an aspect, with regard to downlink centric slot structure 500, acomponent carrier may include a group common PDCCH that carries slotformats for multiple slots. A network entity, such as base station 105(FIG. 1) may execute the downlink control management component 170 toconfigure a component carrier (e.g., CC1) with a longer time durationschedule a component carrier (e.g., CC2) with a shorter time duration orvice versa. In an example, for Case 1, a component carrier (e.g., CC2)with a shorter-slot duration carrying group common PDCCH (or a.k.a.PSFICH) including multiple indications for a component carrier (e.g.,CC1) with a longer-slot-duration and the component carrier itself. Inanother example, for Case 2, a component carrier (e.g., CC1) with alonger-slot duration carrying group common PDCCH including multipleindications for a component carrier (e.g., CC2) with ashorter-slot-duration and the component carrier itself.

In an aspect, cross-carrier group common PDCCH may be disallowed forcomponent carriers of different slot durations. For example, componentcarriers of the same slot duration can be grouped together andcross-carrier indicated. The cross-carrier group common PDCCH indicatormay be carried in the same channel as same-carrier group common PDCCHindicator, or a separate channel. In another example, a single groupcommon PDCCH channel on CC1 indicates slot structure for CC1 and CC2, ora first group common PDCCH channel on CC1 indicates slot structure forCC1 and a second group common PDCCH channel on CC1 indicates slotstructure for CC2.

Referring to FIG. 6, a conceptual diagram of example downlink centricslot structures 600 during transmission of a cross-carrier indicator formultiple component carriers with different numerologies are described.

In an aspect, for UE-specific scheduling, cross-carrier scheduling maybe considered among component carriers of different numerologies. Forexample, if cross-carrier scheduling among component carriers ofdifferent numerologies is enabled, a network entity, such as basestation 105 (FIG. 1) may execute the downlink control managementcomponent 170 to configure a component carrier (e.g., CC1) with a longertime duration (e.g., 15 kHz tone spacing) schedule a component carrier(e.g., CC2) with a shorter time duration (e.g., 30 kHz tone spacing) orvice versa.

In an aspect, for Case 1, a component carrier (e.g., CC2) with ashorter-slot duration carries cross-schedule DCI for a component carrier(e.g., CC1) with a longer-slot-duration. For example, one PDCCH searchspace may include cross-schedule DCI for another component carrier in aslot (e.g., slot 2 n), but not in the next slot (e.g., slot 2 n+1).

In an aspect, for Case 2, a component carrier (e.g., CC1) with alonger-slot duration carries cross-schedule DCI for a component carrier(e.g., CC2) with a shorter-slot-duration. For example, one PDCCH searchspace cross-schedules two or more DCIs for two or more slots (e.g., slotk on CC1 schedules PDSCH or PUSCH on CC2 in slot 2 n and slot 2 n+1). Inanother example, a single DCI on CC1 cross-schedules slot 2 n and slot 2n+1 on CC2 (e.g., joint DCI), which may have some restrictions inscheduling flexibility (e.g., slot 2 n and slot 2 n+1 have the samescheduled MCS).

Referring to FIGS. 7 and 8, conceptual diagrams of example downlinkcentric slot structures 700 and 800 during transmission of UCI formultiple component carriers with different numerologies are described.For example, a UE, such as UE 110 (FIG. 1) may execute the uplinkcontrol management component 150 to configure a component carrier (e.g.,CC1) with a longer time duration to provide uplink feedback for acomponent carrier (e.g., CC2) with a shorter time duration or viceversa. That is, a single PUCCH may provide UCI (e.g., an acknowledgementsignal (ACK), a negative acknowledgement signal (NACK), a schedulingrequest (SR), a Channel Quality Indicator (CQI), or a Channel StateInformation (CSI)) for component carriers of different numerologies.

In an aspect, for Case 1 of downlink centric slot structure 700, onePDSCH has one or more PUCCHs providing hybrid access request (HARQ)feedback. For example, the feedback of UCI for CC1 may be transmitted intwo or more PUCCHs on CC2. In another example, the feedback of UCI forCC1 is only in PUCCH on CC2 in some slots (e.g., slots 2 n, but notslots 2 n+1).

In an aspect, for Case 2 of downlink centric slot structure 800, onePUCCH carries two or more PDSCHs. For example, slot k on CC2 carriesHARQ response for slots 2 n and 2 n+1 PDSCH transmissions.
